After generating a Start condition, the bus master trans-
mits the slave address consisting of a 7-bit device code
(1010000) for the 24LC22A.
The eighth bit of slave address determines whether the
master device wants to read or write to the 24LC22A
(Figure 3-7).
The 24LC22A monitors the bus for its corresponding
slave
Acknowledge bit if the slave address was true and it is
not in a programming mode.
